More than one form

[newToQT]

Hi,

Just using designer so far and am very new to this. I have a main window form, with a menu bar. Now I have designed other forms for when one of the options on the main menu bar is triggered (i.e. an "About this application" form, a "Contact" form etc).

My problem is that I don't know how to show these forms from the main. I mean I double click on the action editor action (using VS2003 integrated with QT 4) and am brought to the app.cpp file with the action created

void protoGUIOne:n_actionProject_triggered()
{

}

Now I've tried lots of things in there to get it to show, but nothing seems to work. I've been looking around but can't find anything.

I relaise this is probably a ridicuosly easy problem but I'm a true newbie and am confused!

Any help appreciated.

when you created main form with needed actions, you should connect these action to slots and then in slots you should create (or show) needed widget.
e.g.

MyMainWindow::MyMainWindow(QWidget *parent)
   : QMainWindow(parent), m_myHelp(0)
{
....
}
....
void MyMainWindow::actionHelp()
{
     if (!m_myHelp)
            m_myHelp = new MyHelpWidget(this);
     m_myHelp->show();
}
...

MyMainWindow::MyMainWindow(QWidget *parent)
   : QMainWindow(parent), m_myHelp(0)
{
....
}
....
void MyMainWindow::actionHelp()
{
     if (!m_myHelp)
            m_myHelp = new MyHelpWidget(this);
     m_myHelp->show();
}
...

To copy to clipboard, switch view to plain text mode 

this is only one variant.

Thanks for replying. I'm still having trouble though.

I'm going through the tutorials (and am feeling really scared!) and see nothing that addresses this in a simple way. I mean I'm just starting yet but want to get this little problem fixed, I knwo it's simple!

I tried doing what you said but still got errors.

In an effort to understand I've just done up a simple program, two forms. One with a pushbutton that opens the other. Still no luck, I thought if I could get that going then any others would be easy.

Is there another way of doing it?

so, I modified your example in which you can see that there is nothing difficult of using signal and slots.
